python小项目之五子棋游戏
本文实例为大家分享了python五子棋游戏的具体代码，供大家参考，具体内容如下
1.项目简介
在刚刚学习完python套接字的时候做的一个五子棋小游戏，可以在局域网内双人对战，也可以和电脑对战
2.实现思路
局域网对战
对于局域网功能来说，首先建立连接（tcp），然后每次下棋时将棋子的坐标发送给对方，当接收到坐标后实例化成棋子对象，这个接收时用了select函数，因为pygame需要循环渲染图片，所以要用非阻塞方式接收消息
select()的机制中提供一fd_set的数据结构，实际上是一long类型的数组，每一个数组元素都能与一打开的文件句柄（不管是Socket句柄，还是其他文件或命名管道或设备句柄）建立联系，建立联系的工作由程序员完成，当调用select()时，由内核根据IO状态修改fd_set的内容，由此来通知执行了select()的进程哪一Socket或文件可读或可写，主要用于Socket通信当中
主要代码如下：
#接收cli的消息
ifis_people:
rs,ws,es=select.select(inputs,[],[],0)
forrinrs:
ifristcpclisock:
try:
data=r.recv(BUFSIZ)
islink=True
print(data.decode('utf8'))
ifdata.decode('utf8')=='again':
is_recieve1=True
ifdata.decode('utf8')=='yes':
is_playagain=True
is_play=True
ifdata.decode('utf8')=='no':
is_recieve2=True
islink=False
ifnotis_playandnotresult:
me=storn.Storn_Black(eval(data))
black_chesses.append(me)
chesses.append(me)
is_play=True
excepterror:
islink=False
电脑对战
电脑对战的思路也很简单，用了应该是最常见的也是最简单的方法，就是循环遍历棋盘的每一个点，判断该点的价值，选取价值最大的点落子，这个需要对五子棋的棋型有一定了解，这里介绍几种常见的棋型（约定1为己方棋子，2为对方棋子，0为空）
活四（011110）：这时候四颗棋子相连，同时两端为空，已经阻止不了一方的胜利了，此时价值应该设置最高
死四（011112|10111|11011）：四颗棋子，只有一个地方能形成连五，如果是自己的棋可以赢，是对方的也可以阻止对方赢棋，此时价值次高
就这样把每种棋型判断一下，获得该点的价值，主要代码如下：
#判断每个点的价值 defpoint_value(pos,white_chesses,black_chesses,identify1,identify2): value=0 foriinrange(1,9): #*1111_活四 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==identify1and\ get_point(pos,i,5,white_chesses,black_chesses)==0: value+=40000 #*11112死四1 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==identify1and\ get_point(pos,i,5,white_chesses,black_chesses)==identify2: value+=30000 #1*111死四2 ifget_point(pos,i,-1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1: value+=30000 #11*11死四3 ifget_point(pos,i,-2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,-1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1: value+=30000 #*111_活三1 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==0: value+=20000 #*1_11_活三2 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==identify1and\ get_point(pos,i,5,white_chesses,black_chesses)==0: value+=20000 #*1112死三1 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==identify2: value+=15000 #_1_112死三2 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==identify1and\ get_point(pos,i,5,white_chesses,black_chesses)==identify2: value+=15000 #_11_12死三3 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==0and\ get_point(pos,i,4,white_chesses,black_chesses)==identify1and\ get_point(pos,i,5,white_chesses,black_chesses)==identify2: value+=15000 #1__11死三4 ifget_point(pos,i,-1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,1,white_chesses,black_chesses)==0and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1: value+=15000 #1_1_1死三5 ifget_point(pos,i,-1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1: value+=15000 #2_111_2死三6 ifget_point(pos,i,-1,white_chesses,black_chesses)==identify2and\ get_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==0and\ get_point(pos,i,5,white_chesses,black_chesses)==identify2: value+=15000 #__11__活二1 ifget_point(pos,i,-1,white_chesses,black_chesses)==0and\ get_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==identify1and\ get_point(pos,i,3,white_chesses,black_chesses)==0and\ get_point(pos,i,4,white_chesses,black_chesses)==0: value+=1000 #_1_1_活二2 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0and\ get_point(pos,i,3,white_chesses,black_chesses)==identify1and\ get_point(pos,i,4,white_chesses,black_chesses)==0: value+=1000 #*1__ ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0and\ get_point(pos,i,3,white_chesses,black_chesses)==0: value+=30 #*1_ ifget_point(pos,i,1,white_chesses,black_chesses)==identify1and\ get_point(pos,i,2,white_chesses,black_chesses)==0: value+=20 #*1 ifget_point(pos,i,1,white_chesses,black_chesses)==identify1: value+=10 returnvalue
电脑选择落子位置时，要判断是进攻还是防守，需要两次遍历棋盘，获取进攻时的最大价值和防守的最大价值，主要代码如下：
#电脑选取落子的位置 defai(white_chesses,black_chesses,chesses): value=max1=max2=0 pos1=pos2=() #进攻时 foriinrange(0,15): row=28+i*40 forjinrange(0,15): col=28+j*40 pos=(row,col) ifis_empty(pos,chesses): continue value=point_value(pos,white_chesses,black_chesses,1,2) ifvalue>max1: max1=value pos1=(row,col) #防守时 foriinrange(0,15): forjinrange(0,15): row=28+i*40 col=28+j*40 ifis_empty((row,col),chesses): continue value=point_value((row,col),white_chesses,black_chesses,2,1) ifvalue>max2: max2=value pos2=(row,col) ifmax1>max2: returnpos1 else: returnpos2
